I-1. Isithuba esiphakathi kwezibonda singabanga mkhulu kune-2.0m, umgama othe tyaba phakathi kweebhodi ezintathu kunye ne-scan, i-scale yodonga igqunywe ziibhodi zesakhiwo esiqingqiweyo. Ukusuka kwi-Lantre ezantsi, kubekwe ungqimba lweebhodi ezili-12m.
2. Ngaphandle kwenqanaba eliphezulu kumgangatho ophezulu, udibaniso lwenqanaba ngalinye kwelinye lomgangatho kufuneka uqhagamshelwe kwi-Butt Fainers xa udlulisa isibonda. Amalungu ezibonda ezimbini ezikufuphi ezithe tye aziyi kumiselwa ngaphakathi kwinyathelo elinye. Umgama ojijekileyo kwicala lokuphakama kwamalungu amabini ahlukaniswe yi-Pole the nkqo kwi-vernnnsise ngaphakathi kwe-500mm: umgama ukusuka embi-mani ophakathi kwendawo edibeneyo ayifanelanga ukuba ingaphezulu komgama. 1/3. Ukuba inyathelo eliphezulu le-Pole lindisiwe ngokugqobhoza, ubude obugqithisileyo akufuneki bube ngaphantsi kwe-1000mm kwaye kufuneka buchazwe ngaphandle kwe-2 ejikelezayo. Umgama ukusuka kumda wePlayiti yeSiphelo sePlayiti kwisiphelo sepali akufuneki ukuba ingaphantsi kwe-10mm.
I-3. Intonga ethe tyaba ethe tyaba kufuneka ifakwe kwindawo ephambili, ifakwe kwi-angle ye-angle ye-angle, kwaye isuswa ngokungqongqo. Umgama ophakathi phakathi kweendlela ezimbini ze-Angle ekunene kwindawo ephambili akufuneki ibe ngaphezulu kwe-150mm. Kwindawo yokuhamba-mbini, ubude bobude bentonga ethe tyaba ngokuthe tyaba ekugqibeleni ngokuchasene nodonga akufuneki bube ngaphezulu kwe-500mm.
4. I-scaffining kufuneka ixhotywe ngezibonda ezithe nkqo kwaye ezithe nkqo. Izibonda ezithe nkqo kwaye ezithe nkqo ziya kumiselwa kwizibonda ezi nkqo kumgama ongaphezulu kwe-200mm ukusuka kwi-Epifulium epithalium esebenzisa i-epitium ye-angle. Xa isiseko sepoli esithe nkqo asikho kwindiza ethe tyaba, ipole esithe nkqo kwindawo ephezulu kufuneka yandiswe ziziphango ezimbini kwindawo engezantsi kwaye ilungiselelwe isibonda esithe nkqo kwaye simiselwe kwiPole elithi nkqo. Ukuphakama komehluko akufuneki kube ngaphezulu kwe-1m. Umgama ukusuka kwi-axis ye-pole ngaphezulu kwethambeka ukuya kwithambeka akufuneki lingaphantsi kwe-500mm.
I-5. Ukuqhekeza i-piule yentsimbi yentsimbi kunye nobude obungaphezulu kwe-24m kufuneka bunxibe ngokuthembekileyo kwisakhiwo usebenzisa i-rigid fortings. Ngomqolo ongatshatanga kunye nokuhamba kabini ngokuphakama okungaphantsi kwe-24m, iinxalenye ezi-rigid udonga lwamalungu kufuneka zisetyenziselwe ukunxibelelana ngokuthembekileyo kwisakhiwo, okanye unxibelelwano oluqhotyoshelweyo lusebenzisa imivalo ye-Tie kunye nenkxaso ephezulu nayo inokusetyenziswa. Kunqatshelwe ngokungqongqo ukusebenzisa iinxalenye zedonga eziguqukayo ezinamanyala kuphela.
I-6. Zombini iziphelo ze-pie ethe tye athe tye kunye ne-pie-pie-pium evele i-scaner Ukuvalwa kwesketwe evaliweyo nge-24m, ukongeza kwiibreyini ezixineneyo ekufuneka zibekwe kwiimbombo, umntu kufuneka asetwa zonke izithuba ezi-6 phakathi. Iibhloko eziguqukayo ze-diaces kufuneka zilungelelaniswe ngokuqhubekayo kwipateni ye-zigzag ukusuka ezantsi ukuya phezulu phakathi kwamacandelo afanayo.
